Is it possible to directly access properties with OCL navigation?
Consider the following relation:
top relation AtoA {
enforce domain source aLeft: simplesource::A{
b=z:simplesource::B{},
str = aRight.b.str
};
enforce domain target aRight: simpletarget::A{
b=z2:simpletarget::B{
}
};
}
I want to produce a consistent output model instance from a input model instance. That means, the output model instance is empty before the transformation.
When the transformation is executed in target direction (empty target model instance), I expect that aLeft.str will not be matched in the source graph since aRight is not bound yet.
Now, when the transformation is executed in source direction (empty source model instance), I expect that the value of aRight.b.str is assigned to aLeft.str.
Is this correct? Can I use arbitary OCL queries to access attributes of a domain element?

Hi
No. Because a complex RHS in a forward direction becomes a complex
pattern match in the reverse direction and if where this is possible,
tooling is liable to be simplistic.
